Allah is our Lord and your Lord. For us our deeds and for you your deeds. There is no dispute between us and you. Allah will assemble us (all), and to Him is the final return."

" Our Lord! In You (Alone) we put our trust, and to You (Alone) we turn in repentance, and to You (Alone) is (our) final Return.
